The present invention relates to the field of virtual presentation systems. More specifically, the present invention relates to three-dimensional presentations of content with interactive feedback capabilities.
Few will argue that the Internet has revolutionized the means and the formats by which human beings communicate today. Specifically, a series of Internet software applications, collectively referred to as the World Wide Web, have brought color, site, sound, and some would even say life to content published on the Internet. The World Wide Web started with a relatively simple interactive search and presentation application called MOSAIC—the world's first web browser. MOSIAC was developed by academics in order to facilitate the sharing of research data located on computer systems at universities around the world. Soon after its development, however, wide spread commercialization of MOSAIC began.
Since MOSIAC's introduction, numerous other web browsers and related software applications have been developed. Whereas MOSIAC presented static content in a two dimensional format, more recent World Wide software applications, such as Flash™ and Real Player™, are capable of accessing and presenting dynamic content such as active containers, streaming audio/video, and various combinations of other multimedia Certain applications have attempted to simulate three dimensional environments over the Internet. For example, some websites allow a visitor to download a software application, commonly referred to as a plug-in, which works in conjunction with the visitor's web browser to simulate a three dimensional environment on the visitors screen. The parameters of the environment (walls, floor, and other containers within the 3-D space) are produced by the site's computer system and several visitors to the site may share and interact within a common environment.
Visitors to web sites providing three-dimensional environments, such as “www.worlds.com”, are usually assigned a virtual representative or agent, commonly referred to as an avatar. The visitor's view of the environment is from the perspective of the avatar, and the visitor navigates the three dimensional environment by directing his avatar to move within the virtual 3-D space. The visitor's view of the environment changes in relation to the avatar's change in perspective. Thus, in order for a visitor to change his view of the environment, he must direct his avatar to move. For the most part, the three dimensional environments of the prior art attempts to emulate a real environment with solid containers and fixed dimensions. A visitor is able to interact with other visitors and with containers such as links by causing their avatar to approach the container.
As part of the present invention there is disclosed a system and method of presenting content in a three-dimensional format. A data container containing one of more parameters representing some portion of the content to be presented is rendered in a virtual three-dimensional environment and assigned a position within the environment. A viewer sees the container from the perspective viewpoint of a virtual agent or avatar traveling along a path through the three-dimensional environment. The container's parameters may be updated as a function of the agent's position. The container's position may also change to create the perception that the container is either traveling towards or away from the viewer's agent. A container may either have persistence, such as a portion of the environment's background, or may be transient, moving in and out of the environment.
One or more of the container's parameters may be an associated function, such that when a user interacts with the container the associated function or functions are initiated or executed. A user may interact wit a container through a variety of input methods. A container's associated function may also be updated and changed as a function of the viewer agent's position within the environment.
The subject matter regarded as the invention is particularly pointed out and distinctly claimed in the concluding portion of the specification. The invention, however, both as to organization and method of operation, together with containers, features, and advantages thereof, may best be understood by reference to the following detailed description when read with the accompanying drawings in which:
It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements.
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the present invention.
Unless specifically stated otherwise, as apparent from the following discussions, it is appreciated that throughout the specification discussions utilizing terms such as “processing”, “computing”, “calculating”, “determining”, or the like, refer to the action and/or processes of a computer or computing system, or similar electronic computing device, that manipulate and/or transform data represented as physical, such as electronic, quantities within the computing system's registers and/or memories into other data similarly represented as physical quantities within the computing system's memories, registers or other such information storage, transmission or display devices.
Embodiments of the present invention may include apparatuses for performing the operations herein. This apparatus may be specially constructed for the desired purposes, or it may comprise a general purpose computer selectively activated or reconfigured by a computer program stored in the computer. Such a computer program may be stored in a computer readable storage medium, such as, but is not limited to, any type of disk including floppy disks, optical disks, CD-ROMs, magnetic-optical disks, read-only memories (ROMs), random access memories (RAMs) electrically programmable read-only memories (EPROMs), electrically erasable and programmable read only memories (EEPROMs), magnetic or optical cards, or any other type of media suitable for storing electronic instructions, and capable of being coupled to a computer system bus.
The processes and displays presented herein are not inherently related to any particular computer or other apparatus. Various general purpose systems may be used with programs in accordance with the teachings herein, or it may prove convenient to construct a more specialized apparatus to perform the desired method. The desired structure for a variety of these systems will appear from the description below. In addition, embodiments of the present invention are not described with reference to any particular programming language. It will be appreciated that a variety of programming languages may be used to implement the teachings of the inventions as described herein.
As part of the present invention, a three dimensional environment which may have data containers is tendered by a rendering module. A data container posses no visible or immutable characteristics, but rather may contain one or more display parameters representing at least some portion of content to be presented to a user or viewer. Data containers may also contain one or more associated functions which may be initiated by a user's interaction with the container. Display parameters may include such characteristics as position, size, shape, color, texture, surface appearance or covering, and movement. A container may have a fixed position or may move in and out of the environment. A container may have an associated message or picture which is mapped onto the surface of the container.
The viewer's view of the environment may be produced by a view production module producing a view from the perspective of a virtual agent passing through the environment. As the virtual agent travels through the environment, the viewer's perspective of the environment and of containers contained therein changes accordingly. Furthermore, display parameters and associated functions of one or more of the containers within the environment may change or be updated by an update module. The update module may update the parameters and/or associated functions in relation to a change in the viewer's perspective. That is, associated functions and display parameters such as shape, color or mapped pictures, of one or more of the containers may change as the virtual agent's position in the environment changes. The associated functions and display parameters may be updated with pre-selected parameters stored on a database, or may change according to input received over a distributed data network.

A container 220 is rendered within the environment in accordance with its display parameters. Display parameters may define such characteristics as position, size, shape, color, texture, mapped pictures or other messages, and movement. A container 220 may have a fixed position or may move within the environment. A container 220 having no display parameters may appear transparent within the environment.
As the virtual agent 100 travels along the path 120, one or more of the containers' associated functions and display parameters may be updated. For example, while the virtual agent is at point 120 a (FIG. 1), container 220 c may have the shape of a triangle and be covered by a first bit map. As the virtual agent approaches point 120 b, the display parameters of container 220 c are updated such that container 220 c is re-rendered as a square covered by a second bitmap.

A view production module 440, generates a two dimensional image representing a prospective view of the environment 200 from the viewpoint of the virtual agent 100. The view production module 440 may use the data set compiled by the rendering module 420 to generate an image for each point along the path 120. Conversion or mapping of a data set representing a virtual three-dimensional environment into a two dimensional image is well known. Commercially available software such as MatLab or even the well known video game Doom are examples of software having view production modules which may be used as part of the present invention.
Turing now to
A parameter update module 460 may update or change the display parameters and associated functions of one or more of the containers 220 in response to a change in the viewpoint of the virtual agent 100. A change in a container's display parameters results in the rendering module 420 re-rendering the container 220 in accordance with the new parameters. A further result of updating the parameters is that the view production module 440 may generate an image showing a container 220 in accordance with the new parameters, thus producing a sudden morphing effect. If a container 220 has parameters defining its movement within the environment, during Step 1500, the container's position may be reassigned. As part of Step 1900, a container's display parameters may be updated, and retuning to Step 1100, the container 220, with any possible changes to its position and parameters, may once again be projected into the environment.
The parameter update module 460 may receive new parameters from storage unit 300. The storage unit 300 may contain a static database of parameters, or the storage unit 300 may dynamically receive new parameters from an external source. A new parameter received from an external source may include an image for covering a container 220, which image represents a message such as an advertisement. Thus, an advertiser, having access to a container's 220 parameter list, may dynamically update any message that container represents.
While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
